LOCK.

SPECIFICATION forming part of Letters Patent No. 439,624, dated November 4,1890.

j Application filed May 28, 1889. Serial No. 312,384. (Model.)

4, the others being immediately in the front and rear thereof, and therefore not shown, contained in holes in the base'plate D2, and which are kept constantly forced against the barrel by springs D. The pins D also enter the holes o2 in the barrel when in line therewith, and thus prevent the rotation thereof, either forward or backward, until forced out by the inner pins D2, contained in such holes, and the key, as is common in the so-called Yale lock, and which therefore needs no further description here.

Loosely mounted on the barrel B are disks E,E, E2, and E3, having alternate notches e and projections e on their peripheries, while the successive numbers from O to 9, inclusive, are printed on such projections. A button EL is attached to each disk E E E2 and a pin E5 inserted between such disk and button. A lug e2 is also formed on the barrel and engages the recess f in the annular trough F,- which is also mounted on the barrel, and caused to revolve therewith by means of the lug e2 and recess f, while a pin f is located within the trough.

The post G, attached to the base-plate D3 of the locking mechanism, is parallel to the barrel B, and carries thereon gear-wheels H, H', H2, and H3, each of which has a crowngearing formed by studs 7L projecting from the sides thereof and a spur-gearing formed by a corresponding number of shoulders h on the periphery. The studs h gear with the notches e of the disks E, &c.,while the shoulders h on the disks H, H', H2, and H3 are struck by the pin f in the annular trough F and the pins on the disks E,E, and E2, respectively.

It will now be seen that if the box A be locked and the numbers on the disks E, E', ttc., are read through the slot a3 in the cover of the box that a rotation of the barrel B, which must be made in order to unlock the box, will cause the pin f in the annular trough F to strike one of the shoulders 7i on l the wheel H, thus moving the latter one tooth T0 a/ZZ whom/ it nty concern:

Be it known that I, WILLIAM FnssENDEN BEASLEY, a citizen of the United States, residing at Oxford, in the county of Granville and State of North Carolina, have invented certain new and useful Improvements in Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide means whereby a lock having a rotatable barrel and a register actuated thereby-such as that described in the patent granted to Henry Clarke, September 30, 1879, and numbered 220,12a-may be adapted to lock the lids of boxes, ttc.; and for this object it consists in attaching a projection upon the rotatable barrel having an are-shaped flange thereon, which is adapted to engage acorresponding fiange upon a fixed catch, as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings, in which corresponding parts are designated b y similar letters, Figure l is a sectional view of my invention applied to a box. Fig. 2 is a top view of the locking and registering mechanisms. Fig. 3 is a front end view of Fig. 2. Fig. 4 is a section on line a: a: of Fig. :2. Fig. 5 is a detail perspective View of the wheels H H', die. Fig. 6 is a detail of the annular trough F. Y

The lid A of the box A is provided with a casing a, which contains the hereinafter-described mechanism, while a catch a is formed in the body of the box to receive the projection l) upon the collar h on the barrel B of the lock. The catch a and projection l) have arc-shaped flanges a2 and b2, respectively, which, by engaging, prevent the opening of the box without first partially revolving the barrel, in which case the projection b takes the position shown in Fig. 3.

In order to prevent a backward rotation of the barrel, it is provided on its rear end with shoulders O, having inclined forward faces c and square rear faces c', which rear faces, if an attempt is made to turn the barrel backward, strike against the inner ends of the outer pins D, (one of which is shown in Fig.

forward, which motion will be transferred to the disk E by means of a stud h and a recess e, the said disk being moved forward the distance of one projection e', and thus the succeeding number will come under the slot a3,

IOO

and it will be seen in comparing the previous reading of the register with the present that the box has been opened. In case the disk E is already recording its highest number (9) and the barrel is turned the pin E5 on the said disk strikes a shoulder 7a of the wheel H', which is thereby moved, transmitting the motion to the succeeding disk E by means of studs h. and recesses c. It is thus evident that on each completed revolution of one of the disks E, E', or E3 the succeeding disk is moved the space of one projection, carrying a proportionally-larger number under the slit a3, and that the first Wheel E represents units, the second E tens, the third E2 hundreds, and the fourth E3 thousands, and that by the above-mentioned system of four Wheels I can register nine thousand nine hundred and ninety-nine revolutions of the barrel B.

The shoulders C on the barrel prevent, as

before stated, the backward motion thereof,

which would otherwise destroy the accuracy of the registration.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is*

l. The combination, in alock, ofa rotary barrel, a projection on one side thereof having an arc-shaped fiange thereon, a catch, also havl lng an arc-shaped flange, engaging the flange WILLIAM FESSENDEN BEASLEY. lVitnesses:
